Product specifications
Digital servo processor and Compact Disc
decoder (CD7)
SAA7377
7.8
DAC interface
The SAA7377 is compatible with a wide range of digital-to-analog converters (DACs). Nine formats are supported and
are given in Table 4. Figures 11 and 12 show the Philips I
2
S-bus and the EIAJ data formats respectively. All formats are
MSB first and f
s
is 44.1 kHz. The polarity of the WCLK and the data can be inverted; selectable by register 7.

DAC interface formats
Note
1.
In this mode the first 16 bits contain data, but if any of the fade, attenuate or de-emphasis filter functions are activated
then the first 18 bits contain data.
